           Summary: mousemove event not registered in frame different from
                    where drag started
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
               URL: http://fumle.dk/drag_issue/
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: pm at one.com


Test case: http://fumle.dk/drag_issue/
The test case is also attached as a zipped file for reference.

Webkit behaves differently than IE and Gecko when dragging an element from one
frame to another when the originating frame has user selection disabled. In
Gecko and IE the mousemove event will be registered in the frame the mouse is
hovering, while in Webkit the mousemove event will be registered in the
originating frame.

An explanation of the test case:
- The background color of the frame where a mousemove event i registered will
turn light green.
- The debugging box in the top right hand corner displays the mouse coordinates
and the filename of the document in the frame where the mousemov event is
handled.

To reproduce:
1) Click and hold the mouse button on the left frame. Move the mouse out of the
frame. The expected behavior is to select text and handle the mousemove event
in the frame the mouse was pressd in.

2) Click and hold the mouse button on the right frame. Move the mouse out of
the frame. The expected behavior from Gecko and IE is to not select any text,
since text selection is disabled for the frame, and to handle the mousemove
event in the frame the mouse is hovering. In Webkit the mousemove event is
handled like when text selection was not disabled.


Reproduced in:
Safari 3.1.2 (525.21) on Windows XP pro
Safari 3.1.2 (5525.20.1) on Mac OS 10.5.4
Safari nightly on Windows XP pro
Safari nightly on Mac OS 10.5.4
